Operating principle and construction

VY-25 is a gear pump designed for high pressure. A reinforced bearing arrangement, a heavy casing section and a mechanical seal make it suitable for continuous duty up to 30 bar. The discharge port is one size smaller than the suction port, which keeps the suction velocity low at high speed. Flow is proportional to speed and independent of pressure. Typical duties are hydraulic power units, high pressure lubrication and press and injection circuits.

Frequently asked questions

Which liquids does VY-25 pump?

VY-25 pumps liquids from 10 to 550 cSt up to 150 °C. Applications: Hydraulic power units; High pressure lubrication systems; Press and injection circuits; Test benches and filling stations.

What is the maximum differential pressure of VY-25?

30 bar in the standard version.

How do I calculate the flow of VY-25?

Theoretical flow = displacement × speed. For VY-25, q = 0.115 l/rev. When viscosity increases, the permitted maximum speed decreases. Use the capacity table in the datasheet and our note on viscosity and speed to select the pump.

Is an ATEX version of VY-25 available?

Yes. The marking is II 1/2G Ex h IIB T4 Ga/Gb, zones 0 and 1. The maximum liquid temperature is 130 °C. Details: ATEX gear pump note.
